 ### Threaded (query performance factor or QPF) search
 - Put both query fields and any projected fields (`RETURN` or `LOAD`) in the index.
 - Set all fields to `SORTABLE`.
 - Set TAG fields to [UNF]({{< relref "/develop/interact/search-and-query/advanced-concepts/sorting#normalization-unf-option" >}}).
 - Optional: Set `TEXT` fields to `NOSTEM` if the use case will support it.

 ## Query optimization

 FT.AGGREGATE jsonidx:profiles '@t:[1299 1299]' 
                 LOAD 6 id t name lastname loc ver 
                 LIMIT 0 10

+                DIALECT 2
 ```
 
 Improvements:
 
 - Targeted projection: the `LOAD` clause specifies only essential fields (`id, t, name, lastname, loc, ver`), reducing memory and network overhead.
 - Limited results: the `LIMIT` clause ensures the query retrieves only the first 10 results, avoiding large result sets.
